I couldn't get a set screw to tighten down on my RCBS die and ended up stripping out the set screw. I contacted customer service and they sent me several set screws and several brass buffers. RCBS customer service is hard to beat. Adding the buffer between the set screw and the die thread works but wondering if there is a better solution.

Anyone else have this issue? After doing some reading on other forums some guys are using split shot as a buffer or changing to the Hornady locking rings.
